Wie betaalt die 489 miljard euro?

Tents of the 'Occupy Frankfurt' movement are pictured next to the Euro currency sign sculpture in front of the European Central Bank (ECB) headquarters during a protest in Frankfurt December 8, 2011. A suspicious envelope sent to Deutsche Bank Chief Executive Josef Ackermann was a letter bomb capable of exploding, investigators said on Thursday. Frankfurt's offshoot of the Occupy protest movement, which is critical of banks and has been staging protests in New York, Washington, London and many other cities, said it had nothing to do with the attempted attack. "We condemn any action that is linked to violence," said Frank Stegmaier, an activist in the Occupy Frankfurt group, which has been camping outside the European Central Bank towers in the German financial capital since mid-October.

Als de Europese Centrale Bank 489 miljard euro uitleent aan Europese banken tegen lage rente, is dat misschien verstandig. Maar wat kost dat eigenlijk?
